Abstract

An X-ray CT apparatus capable of picking up an image of an arbitrary size for an arbitrary part of an examinee. The X-ray CT apparatus prepares two-dimensional data and three-dimensional data from a plenty of X-ray information obtained by making one turn of an X-ray tube and an X-ray information inputting means around a range between a lower jaw and an orbit of a patient, and displays a tomographic image based thereon on a display means. A rotational mechanism part is fitted to a stay, a U-shaped arm with the X-ray tube and the X-ray information inputting means facing each other and fitted thereto is suspended, and the image of an arbitrary size of an arbitrary part of the examinee is captured and displayed by using a chair which is electrically-driven in the vertical direction.
